# Arkansas Highway 19

Arkansas Highway 19 (AR 19) is a designation for two state highways in South Arkansas. One segment of 18.05 miles (29.05 km) runs from the Louisiana state line north to U.S. Route 79B (US 79B) in Magnolia. A second segment of 24.73 miles (39.80 km) runs north from US 371 north across Interstate 30 (I-30) to Narrows Dam at Lake Greeson.

## Route description
### Louisiana to Magnolia

Highway 19 begins at the Louisiana state line as a continuation of Louisiana Highway 159 and runs north to serve as the western terminus for Highway 98 at Walkerville and later the eastern terminus of Highway 160 at Macedonia. The route continues northeast into Magnolia, where the route terminates at US 79B.

### Prescott to Lake Greeson

The route begins in Prescott at US 371 in the northwest corner of town and runs northwest to meet Highway 200, which is a frontage road for I-30. After the I-30 interchange, Highway 19 continues north to intersect Highway 29 before entering Pike County, continuing north to Delight. In Delight, the route begins a westbound overlap with Highway 26 for approximately 12 miles (19 km) to Murfreesboro. In Murfreesboro, Highway 19 splits and runs north to give access to the Greeson Wildlife Management Area, Riverside Use Area, and Narrows Dam Use Area. The route terminates at Narrows Dam at Lake Greeson, where it continues as Beacon Hill Road.

## History

Highway 19 was one of the original state highways, designated in 1926. The route began where US 79 currently crosses the Louisiana state line, and ran north along present-day US 79 to Magnolia. Upon designation, the highway continued north to Prescott via Waldo and Rosston, roughly along today's alignment of US 371 between the communities. In Prescott, the route began a short overlap with Highway 24 to the northwest before splitting and terminating at Highway 26 in Delight. By 1929, Highway 19 was truncated to Highway 26 in Prescott and between May 1934 and April 1935, Highway 19 was replaced by US 79 from Louisiana to Magnolia. Between 1938 and 1939, the northern terminus was extended north to its original terminus in Prescott, and the southern terminus was extended along the route's current alignment to the Louisiana state line along the former Highway 3.
Upon completion of Narrows Dam in 1951, a paved road was built to the structure from Murfreesboro, but was not initially designated a state highway. By 1953, the road had received the Highway 19 designation it carries today. It is the fact that Highway 26 formerly served as a northern terminus that possibly explains why Highway 26, not Highway 19, is the primary route from Delight to Murfreesboro despite having a lower number.
